English Bulldog

If you are thinking about what could possibly go wrong with selective breeding, just have a look at English Bulldog. It’s not just about their short legs or flat face but modern Bulldogs are also more prone to different kinds of health problems. And that’s what has decreased Bulldog’s lifespan to 6.25 years. 

Basset Hound

Believe it or not but Basset Hounds were selectively bred so many times that led to shortening of their face and hind legs. And now the modern Basset Hound can be seen with more skin folds and long ears.


Earlier, Boxers were large with a good face size. But modern Boxer’s faces have become quite short, which invites several kinds of respiratory problems for them. The flattening of the muzzle also makes it difficult for this dog breed to controlling their body temperature.

Bull Terrier

If there is one dog breed that has got the most shocking transformation, it has to be Bull Terrier. Why? Because Bull Terrier used to be very charming and well-proportioned dogs. But now, let’s say they have a football-shaped head. And it does not look that good.

West Highland White Terrier

Saluki (Persian Greyhound)

Although Saluki (Persian Greyhound) has not changed much physically. But the modern breed comes with different eye problems, which is not good.
